Abstract

To assure that an optical pickup can be precisely positioned relative to the loaded disc, a traverse unit positioning in a disc apparatus includes a traverse unit (1) to be mounted in a housing (16) of the disc apparatus, the traverse unit (1) having a substrate and a turntable fixed on the substrate, one end of the substrate is pivotally fixed to the housing via shock-absorbing members (6). A holder (10) attached to the other end of the substrate via another shock-absorbing members (6). The holder (10) having a projection (11) on its outer surface and ribs (12a,12b) on the opposite side walls. A lateral slider (8) is fixed to the housing slidably along the holder and the lateral slider having a cam groove (9) which slopes from lower to higher level. The ribs of the holder are slidably fitted in grooves of stationary guide plates fixed to the housing. The holder is operatively connected to the lateral slider with the projection fitted in the cam groove, thus causing the traverse unit to rise and descend when the lateral slider moves from one to the other side or conversely.
